A Gram-staining-positive, endospore-forming, motile, rod-shaped bacterium, strain AD-1T, was isolated from a tidal flat sediment of the coast of Hwangdo on the Yellow Sea, Korea. Strain AD-1T grew optimally at pH 7.0–7.5 and 40 °C and in the presence of 5–10 % (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain AD-1T was most closely related to Thalassobacillus devorans G-19.1T (98.0 % sequence similarity) and Thalassobacillus cyri HS286T (97.8 %). The cell-wall peptidoglycan was based on meso-diaminopimelic acid and MK-7 was the predominant menaquinone. The major polar lipids were diphosphatidylglycerol, phosphatidylglycerol and two unidentified lipids. The major fatty acids (>10 % of total fatty acids) were iso-C15 : 0, iso-C17 : 0 and anteiso-C15 : 0. The DNA G+C content of strain AD-1T was 45.2 mol%. It appears reasonable to classify strain AD-1T as a member of the genus Thalassobacillus. There were differences in fatty acid profiles and phenotypic and genetic characteristics between strain AD-1T and the type strains of the two Thalassobacillus species. On the basis of the data presented, strain AD-1T represents a novel species within the genus Thalassobacillus, for which the name Thalassobacillus hwangdonensis sp. nov. is proposed. The type strain is AD-1T (=KCTC 13254T =CCUG 56607T).

A novel Tenacibaculum-like bacterial strain, SMK-4T, was isolated from a tidal flat sediment in Korea. Strain SMK-4T was Gram-negative, pale yellow-pigmented and rod-shaped. It grew optimally at 30–37 °C and in the presence of 2–3 % (w/v) NaCl. It contained MK-6 as the predominant menaquinone and iso-C15 : 0, iso-C16 : 0 3-OH and C16 : 1 ω7c and/or iso-C15 : 0 2-OH as the major fatty acids (>10 % of total fatty acids). The DNA G+C content was 33.6 mol%. Phylogenetic trees based on 16S rRNA gene sequences showed that strain SMK-4T fell within the evolutionary radiation encompassed by the genus Tenacibaculum. Strain SMK-4T exhibited 16S rRNA gene sequence similarity levels of 95.2–98.6 % with respect to the type strains of recognized Tenacibaculum species. DNA–DNA relatedness levels and differential phenotypic properties made it possible to categorize strain SMK-4T as a species that is separate from previously described Tenacibaculum species. On the basis of phenotypic properties and phylogenetic and genetic distinctiveness, strain SMK-4T (=KCTC 12569T=JCM 13491T) should be classified as a novel Tenacibaculum species, for which the name Tenacibaculum aestuarii sp. nov. is proposed.
